What are the best practices for SSH security?
To enhance SSH security, consider the following best practices: use key-based authentication, disable root login, and change the default port.
Why is key-based authentication better than password authentication?
Key-based authentication is more secure because it uses cryptographic keys instead of passwords, which can be guessed or stolen.
Should I disable password authentication entirely?
Yes, if possible, disable password authentication to prevent brute-force attacks. Use key-based authentication instead.
What about using a firewall with SSH?
Using a firewall is a great idea! It can restrict access to the SSH port, allowing only trusted IP addresses.
Are there any tools to help monitor SSH access?
Yes, tools like Fail2Ban and OSSEC can help monitor and protect your SSH access by blocking suspicious activity.
